COALGATE, INDIAN TERRITORY;

SWlTCH A TTACHMENT.

SPECIFICATION forming part of Letters Patent No. 517,783, dated April 3, 1894 Application filed June 26, 1893. Serial llo.478.927. (No model.)

To all whom it may concern.-

Be it knownthat we, GOVERNOR D. WAR-v REN, of Dallas, in the county of Dallas and State of Texas, and JAMES CASEY, of Ooal-- gate, Choctaw Nation, Indian Territory, have invented certain new and useful Improvements in Switch Attachments; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which novel features of construction which will be fully described hereinafter and especially pointed out in the claims.

The object of our invention is to provide an improved device for the purpose of preventing cars from running on to the main track from the switch or siding when the latter is closed; and afurther object is to operate the said xdevice in conjunction with the switch throwing mechanism in such a way thatit will be thrown in and outof an operative position at the required time.

"Referring to'the accompanying drawings: Figure 1, is a plan view of a main and side track, showing our improved device applied to the latter. Fig. 2, is a detached perspective viewof the movable shoe. 'j

A designates the main track; B the movable rail thereof; 0 the switch or side track and D the side track movable rail. The outer or free ends of rails B and D are pivoted to transverse barE which extends laterally beneath the switch stand Fin which stand is mounted an operating lever G, which may be of any preferred construction having at its lower end a pivotal connection with the said transverse bar. The outer end of the bar is extended beyond the switch stand and is pivotally secured to the angle iron H, as shown.

J is a safety shoe or block having arm J which is pivotally secured to the switch bed,

This safety shoe or block is preferably arranged adjacent the outside rail of the'switch and has formed upon its upper side an outwardly projecting flange K, which when the shoe is turned upon its pivot projects directly over one of the siding rails and directly in the path of a car wheel when passing out of the switch.

L is a link loosely connected at its inner end to the under side of the shoe J and at its outer end it is pivotally connected to the angle iron M, which is pivoted as shown, adjacent the outer rail of the switch.

The arms H and M of the respective angle ironsH and M' are connected by the wiresN which are extended through at protecting pipe or casing 0, so that when the longitudinally movable bar E ismoved outward for closing the switch the link L will be drawn outward by means of its connection with iron H and Wires N leading from the latter to iron M, thus throwing the flange of the said shoe or block over the rail of the siding so as to effectually obstruct the forward movement of a car upon the siding. When the switch is open with the main track the movement of the abovementioned mechanisms is reversed thus pushing inward the said shoe or block and out of the way of the track, so as topermit an unobstructed passage of the cars from the siding to the main track. Thus it will be seen that the safety device works in conjunction with the switch operating mechanism so that the same movement which closes the switch to the siding sets the safety device,

vent the car from leaving the siding.

The device is simple in construction and may be readily applied to switches now in general use.

Having thus described our invention, what we claim, and desire to secure by Letters'Patent, is-

1. An improved derailing guard comprising a bar pivoted at a point inside of the rail and and the opposite movement which opens the extending parallel therewith, the bar having at its free endtan outwardly extending horizontal flange adapted to overlap the rail, and an outwardly curved vertical flange at the inner side of the horizontal flange.

2. The combination of a side track rail, a shoe pivoted adjacent the same, a means for adjusting the shoe to and away from the rail, and a vertical groove formed in the shoe end, for the purpose substantially as shown and described.

3. An improved derailing guard comprising an arm pivoted at one end at a point inside of the rail, said arm having at its free end a Vertical portion provided with an outwardly extending horizontal flange at a point below the upper edge of the said vertical portion, the vertical portion above the horizontal flange being curved outward at its inner end, for the purpose described.
